Question

A commuter is driving along a highway on which the speed limit is 45 miles per hour when he unknowingly runs into a speed trap involving two police officers. The first officer is positioned at mile marker 145 and clocks the commuter’s car at 45 miles per hour. Five minutes later, a second police officer at mile marker 149 clocks the car at 40 miles per hour. Can the commuter be charged with a speeding violation?

Answer 1

Answer 2

Total distance: 149-145=4 miles
Total time= 5 min= 5/60hour=1/12 hour
average speed= 4/(1/12)=4*12= 48 miles per hour
